One of my amazing laying RIR hens went missing back in September. They got over our fence one night, and we live in town so it's not exactly easy to track them down. This also happened in the middle of the night around midnight. We search the neighboring yard and we found the other chickens but not her. Recently we have been hearing squawking that sounds identical to hers, and we think someone may have found her and just kept her. We never put up missing posters, but it sounds like she is just half a block away or so. Should we knock on a few doors and try to get her back? Or would that be wrong since they have had her for this long? We really want her back now. Should I put missing posters up? Thanks guys.
